+## What is this and who is it for 🤷‍♀️
+
+I do web development and UX design consulting and this is a showcase product I've built in my spare time. It's a very good example of what a modern real-world React codebase looks like.
+
+There are many public React projects out there but most of them are either way too simple or [way too complex](https://github.com/Automattic/wp-calypso). I like to think that this project contains enough complexity to offer valuable insights to React developers of all skill levels while still being relatively easy to understand.
